TROUBLESHOOTING
Before attempting to troubleshoot, be sure all pre-set factory pressure settings are correct. Problems can
stem from these regulators being out of adjustment. to be sure to rule these settings out, they should be checked
first thing. SEE “FACTORY SETTINGS”.
Contaminated air is the cause of most problems that may occur in pneumatic systems. There are Filters that if
maintained properly will perform exceptionally well. However excessive moisture and contamination combined
with lack of maintenance will clog the filters, and if not replaced will finally collapse and allow all the dirt, rust and
crud to enter the system. The best way to avoid problems is to know the air you are using and maintain filters
accordingly. For fewer filter changes take steps to provide clean dry air to the PHX.
The use of the Model 200 Schematic and the Tubing Diagrams are extremely helpful when troubleshooting
the PHX. Have this guide handy if calling Phoenix Unlimited for technical support. Also, assembly drawings are
included in the back of this guide.
The PHX-200 can be function tested for short periods with a standard ¼” shop air hose. Do not run airlock dry
for extended periods. You will need the following items to set it up. Fittings to connect shop air hose to the 1” inlet
on the PHX-200. 1” JIC Cap to cap off blast hose connection. Cap off Airlock outlet at the blast hose connection.
Connect air to the machine. Operate trigger as usual. To operate for longer times, remove and cap off Blue pilot
tube from the Airlock Control Valve, this will prevent the airlock from running dry for too long while you diagnose.
A Note on Tubing Color and Control Systems
When troubleshooting, it is essential to understand the 6 control and distribution systems in the PHX. Each
system is identified by its control tubing size and color. This information will help point you in the right direction.
The systems and respective tubing are as follows:
